Template Method Design Pattenr

Template method design pattern more useful after observer, visitor, command, factory, decorator , single tone and of course facade and adapter :-))), but anyway I think it very nice and not so simple to understand.
Those two reasons, why I would like show this pattern in VERY simple way, I hope it will helps understand this pattern in couple of minutes:

OK, first of all short explanation:

Suppose, we want to prepare for us and tea for friend. We will boil water and after put coffee and tea into the cups. So, we will perform 4 actions:

1. - boil water and put into the cup_1
2. - boil water and put into the cup_2
3. - put coffee into the cup_1
4. - put tea into the cup_2

We have 4 methods and 2 same actions at all (1&2)

So, we can create template method for 1 & 2.
OK, Lets see some code in order to understand it simple:

using System;
 
namespace TemplateMethodPattern
{
    class Program
    {
        static void Main(string[] args)
        {
            var tea = new Tea();
            tea.Create();
 
            var cofee = new Cofee();
            cofee.Create();
 
            Console.ReadLine();
        }
    }
 
    public abstract class TemplateCreateDrink
    {
        public void Create()
        {
            BoilWater();
            AddSomethink();
        }
 
        public void BoilWater()
        {
            Console.WriteLine("Boil Water");    
        }
 
        public abstract void AddSomethink();
    }
 
    public class Tea: TemplateCreateDrink
    {        
        public override void AddSomethink()
        {
            Console.WriteLine("Add Tea to Water");
        }
    }
 
    public class Cofee : TemplateCreateDrink
    {
        public override void AddSomethink()
        {
            Console.WriteLine("Add Cofee to Water");
        }
    }    
}

And...we create template pattern in order to prepare tea and coffee :)
